"Form of Jacob"
The name Jocob is commonly a male name from the "Hebrew" origin.
Jocob is a respelling of Jacob, with the second letter written as o rather than a. No separate root or meaning is attached to the spelling; it is the same name written differently. The form is attested only in United States birth registration data, where it appears intermittently from 1975 onward.
Jacob means "Held by the heel. Replacer. A form of James.".
The pronunciation of Jocob is JOH-kob.
